Beaverhead County Flood Maps Update



Beaverhead County, the City of Dillon, and the Town of Lima are working with the Federal Emergency Management Agency (FEMA) and Montana Department of Natural Resources and Conservation (DNRC) to update and produce new floodplain maps for the Beaverhead River, Blacktail Deer Creek, Selway Slough, Junction Creek in Lima and other flow splits from the Beaverhead River and Blacktail Deer Creek. Updated floodplain maps will depict the latest, most accurate flood risk data, and will eventually replace FEMA’s existing floodplain maps which are based on data from the late 1970s.

New Flood Insurance Rate Maps from this project are not expected to be finalized for a while – the study information and maps need to go through a technical and public review process 

When finalized, the new maps could have effects on some property owners in mapped floodplains (see Floodplain FAQs page for more information).

Public Meetings Held

The County, City and Town hosted two Public Open Houses to help property owners review the draft maps.  The meetings were held in Dillon on May 9, 2019 and in Lima on May 13, 2019.

Additional public meetings will be scheduled in the future.  Check back for updates or contact your county, city or town Floodplain Administrator (see contact information on the right) or with Montana DNRC. 


Provide comments on the draft maps and reports

We welcome your questions and feedback on the draft maps and reports.  Please submit any comments or feedback directly to your County, City or Town Floodplain Administrator so they can forward the information to FEMA and DNRC.  Later this year, FEMA will open an official comment and appeal period on the maps and information.  Check back here to stay informed on the specific dates of FEMA's appeal and comment Period (estimated early 2020). 


Come back for more information

We will update this website with new, relevant information as this project progresses.


Know your property's flood risk

Flood Insurance Rate Maps indicate areas of flood risk. Once this project is complete, updated Flood Insurance Rate Maps will provide more accurate, current, and detailed data and mapping of flood risk areas.
